如何将日历对象转换为ISO8601格式的DateTime字符串？

import datetime

def convert_to_iso8601(calendar):
    iso8601_datetime = calendar.strftime('%Y-%m-%dT%H:%M:%SZ')
    return iso8601_datetime

# 示例用法
calendar = datetime.datetime(2022, 1, 1, 12, 30, 0)
iso8601_datetime = convert_to_iso8601(calendar)
print(iso8601_datetime)

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class CalendarConverter {
    public static String convertToISO8601(LocalDateTime calendar) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss'Z'");
        String iso8601DateTime = calendar.format(formatter);
        return iso8601DateTime;
    }

    // 示例用法
    public static void main(String[] args) {
        LocalDateTime calendar = LocalDateTime.of(2022, 1, 1, 12, 30, 0);
        String iso8601DateTime = convertToISO8601(calendar);
        System.out.println(iso8601DateTime);
    }
}
